Which of the following would count as evidence that two populations are different species, according to the biological species concept?.
Step by step
Solved in 2 steps
- Which of the following is not part of how we define a species? a. Its individuals appear different from other species. b. It is reproductively isolated from other species. c. Its populations can interbreed. d. Fertile offspring are produced.n which situation would it make sense to use the morphological species concept? When you are able to collect data about how individuals in your study use their habitat, but you are unable to determine if they interbreed When working with fossils from extinct organisms When you only have genetic data about each organism in your study When you are not able to collect data about how individuals in your study use their habitat, but you are able to collect reproductive dataBird guides once listed the Myrtle warbler and Audubon's warbler as distinct species, but applying the biological species concept, recent books show them as eastern and western forms of a single species, the yellow-rumped warbler. Experts must have found that the two kinds of warblers: Question 10 options: live in the same area. successfully interbreed in nature. look enough alike to be considered one species. are reproductively isolated from each other. are allopatric.
- Use each of the following species concepts to write a claim about whether the dark and light fur mice are, in fact, different species. Your claim should demonstrate your understanding of that particular species concept. Mice with light coat colors are found in populations scattered across the southeastern US. Researchers believe the light coat color emerged in a single population. How would a biologist explain the evolution of the light coat color in populations across the southeastern US? Briefly explain your reasoning.Which of the following are post-zygotic reproductive barriers?a. Different mating songs prevent mate recognitionb. Species A breeds in Spring, Species B breeds in summerc. Species A and B mate, but the embryos die before hatchingd. The gametes of species A aren’t compatible with the gametes of species Be. Species A and B can mate and produce healthy offspring, but the offspring are infertileWhat are examples for gene flow? Select all that apply A distinct population of iguana drift to a new island that is already inhabited by members of the same species. A small population of humans colonizes a newly formed island. A fire drastically reduces the size of a white-tailed deer population. The remaining individuals spread out throughout the remaining forest. Wind blows pollen from one population of plants to another and cross-fertilization occurs. n An earthquake results in the formation of a canyon, splitting a population of toads apart.
- Which of the following forms of reproductive isolation illustrates a prezygotic barrier to gene flow? O Species A forms hybrids with species B and the hybrids are able to breed back with either of the two parent species to produce healthy fertile offspring. O Two closely related birds, the lazuli bunting and indigo bunting, sing similar songs to attract mates and even though human ears can not distinguish them the females never make wrong choices in choosing who to mate with. O Two species of turtles living in a large lake have different ecological requirements and never interact. O Several species of corrals in a Honduras corral reef release gametes about the same time but inter- specific attraction of gametes does not occur. O All but one of these illustrates a type of prezygotic barrier to gene flow.Consider two species that diverged while geographically separated but resumed contact before reproductive isolation was complete. Predict the outcome over time if the two species mated indiscriminately and (a) hybrid offspring survived and reproduced more poorly than offspring from intraspecific matings or (b) hybrid offspring survived and reproduced as well as offspring from intraspecific matings.In the 1890s, hunting reduced the northern elephant seal population to only 20 individuals. Due to conservation efforts, their population size today is above 30,000. How would the genetic diversity of the northern elephant seal population compare to the genetic diversity of the southern elephant seal population, which was not heavily hunted? * The northern elephant seal would have much less genetic variation than the southern elephant seal. The southern elephant sea would have much less genetic variation than the northern elephant seal. The two populations would have similar genetic variation. The southern elephant seal would have stable genetic variation because it is in Hardy- Weinberg equilibrium. You are studying two variations of banana slugs. They have similar coloration and live in the same habitat. Although they are physically able to mate, there are no offspring that survive embryologic development. What can you conclude about the banana slugs? *
- Which is most likely to happen to a population that becomes anatomically isolated from the rest of its species? The entire species will become extinct. The population will become a separate species over time. The population will breed with a different species nearby. O The entire species will continue to have viable offspring together.Consider this example. Shorebirds on the Eastern coast of North America feed on the mollusks and tiny crabs along the shore. Birds with tougher beaks are better adapted to crack open the shells of the mollusks, and birds with sharper beaks are better adapted to pierce the shells of crabs. Over time, the shorebirds become two separate species that no longer breed with one another. What type of speciation has occurred? A. Sympatric speciation B. Adaptive speciation C. Microevolution speciation D. Allopatric speciationPlease make a concept map only Why has the evolution of resistance to insecticides in mosquitoes been so rapid? Consider the effect of population size, reproduction cycle, mutation rates, natural selection and genetic drift. Accompany your answer with a concept map (of the interactions of the different key terms, i.e., small population versus big population).
